IMPROVEMENT IN PLOW-BEAMS.

Specification forming part of Letters Patent No. 23,024, dated February22, 1859.

To all whom it may concern:

Be it known that I, JOHNS. HALL, of Manchester, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Iron or Steel Beams for Flows; and I do hereby declarethe following to be a full, clear, and exact description of theconstruction and operation of the same, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure 1 represents in perspective a plow constructed with one of thebeams in question. Fig. 2 represents a vertical cross-section throughthe beam and a portion of the standard to show how they are braced andunited together. Fig. 3 represents a longitudinal horizontal sectionthrough the beam.

Similar letters of reference, where they occur in the several figures,denote like parts of the plow in all of them.

My object is to make an iron plow that will be strong, durable, andcheap, and with-a1 light and of easy drat't.

1am fully aware that tubular beams and handles have been proposed in theconstruc tion of plows and other agricultural implements; but thedifficulty of uniting the several parts of the plow to such tubularforms i has rendered them of no available use whatfacilities foruni'ting'the other parts of the plow to it as to make this form ofplow-beam very desirable and economical.

To enable others skilled in the art to make and use my invention, I willproceed to describe the samewith reference to the drawings.

A. represents a plow, which may be of any of the usual well-known formsof construction.

B are the handles, which for lightness and strength may bemade ofangle-iron, and braced in any of the usual ways.

G is an iron or steel beam, of an inverted-U form. This beam may he ofrolled iron or steel, and made in bars of any length, and cut intoproper lengths for a plow-beam or it may be struck up into its properform with suitable dies and pressure out of plate metal, or turned overa formeroperations that are familiar to mechanicians.

The ends of the beam (1, when out to the proper length, may be heatedand welded into a solid instead of a hollow form to admit of its rearbeing united to the handle, and making suitable provision at'its pointfor the ring I) or elevis, to which the team is hitched.

c is the standard of the plow; it passes up into the hollow of the beam,and the two are secured together by a screw-bolt or rivet, d, as shownin Fig. 2. The thickness ot'thestaudard may be such as to snugly tit thehollow of the beam, and when the beam and standard are bolted togetherthey mutually strengthen and support each other by a very simplejunction. In casting, a hole may be left in the top of the standard, andthe flanges ot the beam are punched through to form the bolt-hole.

e is a brace for bracing the standard and beam. The forward end of thisbrace passes up into the hollow of the beam, and is secured thereto by ascrew-bolt or otherwise, and is entirely protected by the flanges of thebeam, so that nothing will catch or hang to it.

The shape of the beam when finished and ready to he joined to the otherparts of the plow can'be seen at Fig. 3. It is in its best form forstrength, and particularly in its best form for being secured to theother necessary parts of the plow. A beam of this kind,- that weighssome twelve pounds, will be strong enough to resist all the strain towhich a plow is ordinarily subjected, the first cost of which wouldnotexceed fifty cents.

Of course heavier plows would require heavier beams at a greater cost.

Having thus fully described the nature and object of my invention, Iwould state that I do not claim a tubular plow-beam; but

What I do claim as new, and desire to secure by Letters Patent, is-

An iron or steel plow-beam of an inverted-U form throughout its mainlength, and welded or compressed at its ends, and so made as to becapable of receiving the top of the stand ard into its hollow portion,and be otherwise conveniently connected to or with the other portions ofthe plow, and so as to make a cheap and efficient junction of theseveral parts thereof, and produce a cheap, strong, and durableplow-beam, as herein set forth.
